FAQ
- MATLAB gives me the splash screen, then just sits there...
- Go to a terminal window and type "ps -u NETID" with your NET ID. There should be a process called "matlab". Get the number off it, then type "kill -KILL NUMBER" (the adverb really is "-KILL"). Then, go to your root directory, change into the .matlab directory and remove the contents with "rm -ir *" (make SURE you are in the .matlab directory). Go back to where you were and start matlab again.
- MATLAB on Unix just sits there - I think I created an infinite loop! Or I am running a program that will take a significant fraction of forever to complete...

- Hit CTRL-C to break out of Matlab.
- How do you even get IN to MATLAB? I have no idea...
- How do you type MATLAB code in these pages, and how do you make it pretty?
- The SyntaxHighlighting extension is installed on this wiki, so all you have to do is use the appropriate source and lang tags. The code:
<source lang="matlab"> %% Post-processing % take data from AI [data, time] = getdata(AI); %% plot data c1 = data(:,1); c2 = data(:,2); c3 = data(:,3); c4 = data(:,4); plot(time, c1, 'b-', time, c2, 'g--', time, c3, 'r-.', time, c4, 'c:') legend('0', '1', '2', '3', 0) xlabel('Time (s)'); ylabel('Voltage (V)'); </source>
- produces
%% Post-processing
% take data from AI
[data, time] = getdata(AI);
%% plot data
c1 = data(:,1); c2 = data(:,2); c3 = data(:,3); c4 = data(:,4);
plot(time, c1, 'b-', time, c2, 'g--', time, c3, 'r-.', time, c4, 'c:')
legend('0', '1', '2', '3', 0)
xlabel('Time (s)'); ylabel('Voltage (V)');
